Sanaei 7605902324 Test-quality audit: fix 2 prod bugs, strengthen weak tests, add mutation/fuzz/CI tooling (#5345)
* test(audit): add gremlins/rapid/coverage tooling + AUDIT.md scaffold

* test(audit): hygiene sweep (race-clean except logger global; Finding #2) + smell inventory

* test(audit): cover untested error/edge branches (TLS proxy+pin, migration tag cleanup=Finding #1)

* test(audit): strengthen internal/sub link tests (dedup key, TLS/Reality mapping, clash well-formedness)

* test(audit): property (rapid) + fuzz tests for joinHostPort/userinfo/pin/ParseLink

* test(audit): tighten frontend subSortIndex rejection assertions + wire coverage

* ci(audit): add shuffle gate + non-blocking race job (Finding #2) + fuzz-smoke; document mutation policy

* chore(audit): gitignore frontend coverage output

* test(audit): exhaustive whole-repo pass — strengthen 5 weak/fake tests (netproxy, CSP, modal per-protocol loops, schema coercions)

* docs(contributing): add Testing section (conventions, race/shuffle, fuzz, mutation policy); drop AUDIT.md ledger

* fix(logger,migration): guard logBuffer with mutex; execute legacy tag cleanup (tx.Exec); make CI race gate blocking

* ci(mutation): add nightly scoped gremlins workflow (informational artifacts)

* test(audit): strengthen runtime tests — baseURL scheme/port bounds, isNonEmptySlice, trafficReset

* test(audit): strengthen clash tests — reality field mapping + tcp-header validation

* test(audit): runtime — egress-proxy + content-type tests; drop redundant bp=='' branch

* test(audit): strengthen link parser/helper tests (defaultPort, splitComma, base64, canonicalQuery, tls/reality/transport mapping)

* test(audit): strengthen sub/xray/common/netsafe/mtproto/config/middleware tests (kill surviving mutants)

* test(audit): raise timeout on protocol-iteration modal tests (heavy re-renders, slow on CI)

* fix(logger): GetLogs returns at most c entries (off-by-one fix; addresses PR review)

* perf(logger): snapshot logBuffer under lock so GetLogs doesn't block logging; clarify fuzz-seed docs (addresses PR review)
